Dual-Channel MIPI® DSI to Dual-Link FlatLink™ LVDS Bridge - SN65DSI85


Dual-Channel MIPI® DSI to Dual-Link FlatLink™ LVDS Bridge



The SN65DSI85 DSI to FlatLink bridge features a dual-channel MIPI D-PHY receiver front-end configuration with 4 lanes per channel operating at 1 Gbps per lane; a maximum input bandwidth of 8 Gbps. The bridge decodes MIPI DSI 18-bpp RGB666 and 24-bpp RGB888 packets and converts the formatted video data stream to a FlatLink compatible LVDS output operating at pixel clocks operating from 25 MHz to 154 MHz, offering a Dual-Link LVDS, Single-Link LVDS, or two Single-Link LVDS interface(s) with four data lanes per link.

The SN65DSI85 is well suited for WQXGA (2560 × 1600) at 60 frames per second, as well as 3D Graphics at WUXGA and True HD (1920 × 1080) resolutions at an equivalent 120 fps with up to 24 bits-per-pixel. Partial line buffering is implemented to accommodate the data stream mismatch between the DSI and LVDS interfaces.

Designed with industry-compliant interface technology, the SN65DSI85 is compatible with a wide range of micro-processors, and is designed with a range of power management features including low-swing LVDS outputs, and the MIPI® defined ultra-low power state (ULPS) support.

The SN65DSI85 is implemented in a small outline 5-mm × 5-mm PBGA at 0.5-mm pitch package, and operates across a temperature range from –40ºC to 85ºC.
